Anahid can purchase 9 drawing tablets for $10.26 at the art supply shop. She can purchase 21 of the same tablets for $23.52 from

bazaltina [42]

Buying from the website is a better deal.

The amount saved <u>per tablet</u> by purchasing at the vendor with the better deal is $0.02

<h3>Calculating cost </h3>

From the question, we are to determine the better deal

From the given information,

Anahid can purchase 9 drawing tablets for $10.26 at the art supply shop

The unit price at the art supply shop is

$10.26/9 = $1.14

Also,

She can purchase 21 of the same tablets for $23.52 from a website

The unit price from the website is

$23.52/21 = $1.12

Since, the unit price from the website is lesser, it is the better deal

The amount saved per tablet by purchasing at the vendor with the better deal is

$1.14 - $1.12 = $0.02

Hence, buying from the website is a better deal.

The amount saved <u>per tablet</u> by purchasing at the vendor with the better deal is $0.02

Simple interest of 668 5% 2 years

ludmilkaskok [199]

Answer:

$66.8

Step-by-step explanation:

The formula for simple interest is |=prt.

P=Principal R=Rate T=Time

Now you plug the numbers in |=668*0.05*2

Multiply 668*0.05= 33.4

Then you multiply that by 2= 33.4*2=66.8

That is your answer.

Use Newton’s Method to find the solution to the equation

Scorpion4ik [409]

$f(x) = - x {}^{2} + 18 \\ f'(x) = - 2x$

$x_{n + 1} = x_{n} - \frac{f(x_{n})}{f'(x_{n})}$

$x_{2} = 3 - \frac{f(3)}{f'(3)} = 4.5$

$x _{3}= 4.5 - \frac{f(4.5)}{f'(4.5)} = 4.25$

$x_{4} = 4.25 - \frac{f(4.25)}{f'(4.25)} ≈4.242647$

$x_{5} = 4.242647 - \frac{f(4.242647)}{f'(4.242647)} ≈4.242640 \\$

Given a mean earth radius of 20,906,000 ft, and an observation latitude of n 42 degrees, what is the arc distance of one second

murzikaleks [220]

Answer:

arc second of longitude: 75.322 ft
arc second of latitude: 101.355 ft

Explanation:

The circumference of the earth at the given radius is ...

2π(20,906,000 ft) ≈ 131,356,272 ft

If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...

(360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle

Then one arc-second is

(131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second

__

Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.

_____

<em>Comment on these distance measures</em>

We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
